Piezoelectric Microgripper

Application ID: 4695

This tutorial models a piezoelectrically actuated microgripper with mechanical contact. The microgripper contains a piezoelectric actuator that operates in the longitudinal mode. Elongation in the longitudinal direction creates a lifting movement to the structure. Simultaneous contraction in the transversal direction closes the gripper and allows it to move objects. The model uses the Piezoelectric Devices interface.

This model is included as an example in the following products:
